A simple flotation device used to measure density is the hydrometer. It is a sealed tube with a narrow part at one end and some very dense material such as lead at the other. Such a tube if made correctly, floats vertically so that the narrow part sticks out of the liquid while the heavy end sinks. The narrow part is calibrated for density. The hydrometer floats higher in liquids of
